Abstract


The purpose of this study was to determine effect of lime concentration in the gelatin manufacture from goat skins in terms of physico-chemical and to determine the best lime concentration that can be used for gelatin manufacture from goat skin. The materials used were 5 sheets of Ettawah crossbred goat skin aged 1.5-5 years and lime (Ca(OH)2). The results showed that different lime concentration in the curing process during the manufacture of goat skin gelatin had no effect (P>0.05) on the yield, viscosity, pH, water content, protein content and fat content. The best treatment was the use of 5% of lime concentration which resulted 12.82% of yield, 3.67 cP of viscosity, 2.7 of pH, 9.29% of water content, 73.58% of protein content and 1.77% of fat content.
